specification.

This invention relates to resilient connector weights, and pertainsespecially to aresilient connector adapted to be attached to a cable ona well rig andto an elevatorhook, and which also serves as a weight forthe cable.

In coupling or uncoupling sucker rod joints difiiculty is ex eriencedbecause of the joints getting out o alinement causing the threads to jamand to become mutilated. Further, difficulty is experienced by reason ofthe weight of the upper joints coming on the lower at the threadedconnection making it difficult to couple or uncouple the joints andtending to bur the threads.

An object of my invention is to provide a resilient connector which willlift the weight of the upper joint and keep it in alinement while beingcoupled or uncoupled.

In using a cable rove over a sheave at the top of a well rig forelevating sucker rods it is a common practice to attach a weight to thefree end of the cable, when it is detached from the sucker rod, therebykeeping the weight of the cable from pulling it over the sheave.

Another object of my invention is to provide a connector which willserve as a weight to obviate the above recited objections.

I accomplish these objects by means of an embodiment of my inventionillustrated in the accompanying drawing, in which:

Figure 1 is a vertical section through my improved resilient connectorweight. Fig. 2 is a section as seen on the line 22 of Fig. 1. Fig. 3 isa section as seen on the line 3-3 of Fig. 1.

Referring more particularly to the drawing, 4 denotes a cylindricalshell having a bore of several diameters. Theportion of small diameterat one end thereof is indicated by 5, a bore of enlarged diameter by 6,and of greater diameter at the upper end thereof at 7. Two shoulders areformed within the bore of the body and are indicated by 8 and 9. Theexterior of the body 4 is reduced in diameter at the upper end andthreaded as indicated at 10.

A cap 11 is detachably secured to the body 4 and is constructed with abore 12 of the same diameter as the bore 7 and forming a continuationthereof. The cap is counterbored at the lower end and threaded to engagethe threads'on the portion 10 of the body 4. A bore of reduced diameteris formed at 13 so that a shoulder 14 is formed which acts as a bearingsurface for a stem.

Extending into the bore of the body is a sectionof cable 15 having atthe upper end thereof ahead 16 which is disposed within the portion 7 ofthe bore and when in its lowermost position is adapted to abut theshoulder 8. Surrounding the cable 15 and interposed between the head 16and the shoulder 9 is a, spring 17 forming a resilient supporting memberfor the cable 15.

At the upper end and within the cap 11 is a stem having a shank 18 whichextends through the bore 13 and is provided with a head 19 disposedwithin the bore 12. The shank 18 is reduced in diameter at its upper endas indicated at 20, threaded, and adapted to receive a cable socket 21or any other means for coupling a cable 22 to the stem. The socket 21 ofthe cable 22 does not form any part of my invention but merely shows theusual means for connecting an elevating cable to my connector. The cable22 in usual practice extends over asheave at the top of the well rig.

The lower end of the cable 15 is looped and adapted to be connected tothe clevis 23 of a hook which is commonly enga ed with a sucker rodelevator. The spring 1 is so designed that it will support the weight ofa sucker rod joint, and when the connector is attached to the sucker rodas it is unscrewed from a lower joint the upper joint will be graduallylifted takin weight off the threaded connections an keeping the suckerrod joints in alinement.

In order to permit free swiveling and turning of the sucker rod joint 1have provided a ball bearing between the head 19 of the stem and the cap11. This bearing comprises a ball race-way 24 mounted on the head 19 anda race-way 25 disposed against the shoulder 14 with balls 26 interposedbetween the race-ways.

When the sucker rods are detached from the connector the weight of theconnector is sufficient to hold the end of the cable 22 from runningover the sheave.

The advantages of my improved connector are obvious from the abovedescription, and it eflects a great saving in labor and in damagedparts.

What I claim is:

1. A resilient connector weight for Well rigs, comprising thecombination "of a shell of relatively great weight, a stem securedthereto by a swivel connection for attach- -ment to a cable, a hooksecuring member slidably secured to said shell, and resilient meansinterposed between said member and said shell, said shell provided withmeans to relieve the pressure on said resilient means when compressed apredetermined amount.

2. A resilient connector weight for well rigs, comprising thecombination of a shell of relatively great weight having an axiallyextending bore of enlarged diameter intermediate its ends therebyforming a shoulder at the upper end, a securing member adapted forattachment of a hook extending into said bore, a head on said member, are silient member mounted between said head and the end of said shellsupporting said members, said head arranged to abut said shoulder torelieve the pressure on said resilient member when compressed apredetermined amount, and a stem having a head disposed in said enlargedportion of the bore and below said shoulder forming a swiveledconnection between said shell and said stem.

3. A resilient connector weight for well rigs, comprising thecombination of a shell of relatively great weight having an axiallyextending bore of enlarged diameter intermediate its ends therebyforming an upper and lower shoulder, a hook securing member extendinginto said bore having at its upper end a head disposed'in the enlargedportion of said bore, a spring between said head and said lowershoulder, said head arranged to abut said shoulder to relieve thepressure on said spring when compressed a predetermined amount, a stemadapted to be attached to a cable having a head disposed in the enlargedportion of said bore.

anti-friction bearing means between said upper shoulder and the head onsaid stem.

In witness that I claim the foregoing l have hereunto subscribed my namethis 23rd day of February, 1916.
